How to use

Fill the transparent water tank with clean water up to the recommended level, connect the unit to a power source using the supplied USB cable or an appropriate AC adapter, and switch the cooler on using the front control buttons. Select one of the three fan speed settings to adjust airflow intensity; LED indicators will show the current operating mode. Replace or refill the water tank as needed for continuous evaporative cooling and switch off the device before moving or refilling.

Recommendations

For best performance, position the cooler on a stable, level surface with unobstructed airflow and use in moderately ventilated rooms. Use clean water and empty the tank if the cooler will be unused for extended periods. Do not add oils or other additives to the water tank. When using AC power, ensure the adapter and USB cable are rated for the voltage in your region.
